The first thing I'd do is run chkdsk X: /r on all the partitions on the drives. Replace the X with the drive letter of the partition being checked. A reboot will likely be required for some partitions.

Does the second computer you tried it on have the same motherboard and other hardware as the first one? If so, the problem may be a poor fit of the Linux drivers present on the CD - this is often the problem if the boot CD doesn't work when the Windows version does. Have you tried the Windows version to create an archive and validate it?

That is strange alright. Which usually means something has changed from when you sucessfully ran the program. Was there any hardware upgrades/changes done to the machine from the time it first ran? Are you sure you are running TI exactly the same way as when you sucessfully ran it?

Are these Windows-based machines? What filesystem is on the hard-drive?

I would recommend to try another CD based on ISOLINUX. We have implemented the possibility to download the appropriate ISO file after logging in to your account (the serial number should be registered). Please log in to your account, go to the Registered products section -> Bootable media. Download the file.

You can find more information on how to burn an ISO image to a CD here and here .

Check the functionality. If this doesn't help, please check the memory module for corruption.

Please download one of the archives depending on what media type you are going to use:
